Answer:

Total \:area\approx 290.5\: ft^2

Step-by-step explanation:

Total area =\frac {1}{2} \pi r_1^2 +\frac {1}{2} \pi r_2^2

(where r_1 = 22/2 = 11 \: ft, \: \:\:r_2 = (30-22)/2 = 4 \: ft)

\therefore Total \:area=\frac {1}{2} \pi( r_1^2 +  r_2^2)

\therefore Total \:area=\frac {1}{2} \times 3.14(11^2 + 8^2)

\therefore Total \:area=1.57(121 + 64)

\therefore Total \:area=1.57(185)

\therefore Total \:area=290.45\: ft^2

\therefore Total \:area\approx 290.5\: ft^2

Given: BC bisects DBE. Prove: ABD is congruent to ABE
Arada [10]

Answer:

See below

Step-by-step explanation:

BC bisects <DBE and if AC is a straight line then you have that:

<ABD + <DBC = 180 (straight angle because of line AC)

<ABE + <CBE = 180 ( straight angle because of line AC)

Because BC bisects <DBE =>   < DBC = <CBE

So <ABD and <ABE must be the same to both sum 180 when added < DBC
